I feel sorry for the driver.
Im not saying its the police's fault far from it, but if the police where tough with people like they should be then the driver who hit her would not have a smashed car and probably shock.
The police should have handcuffed them and put them in the back of the car as soon as they reached them. Then questioned them at the station not on the hard shoulder.
I feel the police no longer prevent crime they are always reacting to it.
The sisters look like a pair of smack heads, im sure they will have had contact with the police and probably mental health before and that’s another point of prevention that will have been missed by today’s poor attitudes.
